Dazakoot 16" Tender Spring Kit for Trailers (2PCS) — Galvanized 16" Springs with Sleeve & Stainless Hangers

Dazakoot 16" Single Tender Spring Kit (2PCS) protects trailer air and electrical lines by suspending them off the ground and reducing wear while driving and backing.

This two-piece tender spring kit is engineered for trailers and semi trucks to keep air hoses and electrical lines from dragging, snagging, or rubbing against suspension components. Built from galvanized carbon steel with a protective sleeve and robust stainless-steel hangers, the kit replaces common OEM parts and fits many 3-in-1 air-line setups. It’s a compact, affordable way to reduce service calls, prevent cable damage, and make routine trailer hookups neater and safer.

How does this spring protect trailer lines?

The Dazakoot tender spring holds air and electrical lines up and away from the road surface and suspension pivots. Its spring action absorbs movement and prevents sudden jerks from stressing fittings and connectors. The external sleeve prevents tangles and sun damage while the hanger bracket keeps the assembly secured to the frame.

• 16" spring length for common trailer clearance needs
• Galvanized finish guards against rust and weathering
• Protective plastic sleeve prevents chafing and UV exposure
• Stainless-steel hanger with rubber cushion for secure mounting

Will this fit my trailer or semi truck suspension?

The kit is designed for wide compatibility with standard 3-in-1 air-line arrangements on trailers and tractors. It replaces many OEM tender springs and fits most suspension rod diameters using the included additional hook. Check your trailer’s mounting points and rod size to confirm fitment before installation.

• Replaces Tectran 9820-1, 9420-1 and similar OEM springs
• Includes extra hook for varied suspension rod diameters
• Works with typical 3-in-1 air and electrical line kits
• Simple brackets allow retrofit without major modifications

How durable is the Dazakoot tender spring under regular use?

The spring is formed from carbon steel and hot-dip galvanized to resist corrosion and maintain elasticity under load. It supports up to 30 lbs and includes stainless-steel hangers with rubber cushioning for long-term durability in road conditions. These materials minimize rust, breakage, and premature wear even in wet or salty environments.

• Carbon steel core for reliable spring tension
• Galvanized coating for corrosion resistance
• 304 stainless-steel hangers reduce rust and flex fatigue
• Rubber cushioned clamps protect hoses and fittings

How easy is installation and maintenance?

Installation is straightforward for technicians or experienced operators: mount the hanger, attach the spring, route lines inside the sleeve, and choose the included extra spring if dual support is needed. Maintenance is largely visual—inspect for sleeve damage, hanger tightness, and spring corrosion periodically, then replace parts as needed.

• Quick bolt-in hanger installation
• Slide-in sleeve keeps lines secured and organized
• Optional second spring for temporary or alternate setups
• Low-maintenance design with simple periodic inspections

Who is this for: fleet managers, owner-operators, truck service shops, and DIY trailer owners who need a reliable, low-cost solution to keep air and electrical lines off the ground. If you run trailers frequently, perform hookups often, or operate in wet or corrosive environments, this Dazakoot 16" tender spring kit helps reduce line failures, simplify inspections, and extend the life of plumbing and wiring on your rig.
